It's time for school to get back in session and if you think the biggest actors and actresses were only in drama club and musicals growing up, think again.

They were cheerleaders, prom kings and homecoming queens, sang in choir, and governed their student bodies.

If you've ever wondered what kind of students your favorite celebrities were, we rounded up what some of the biggest names in Hollywood were up to during their formative years. Classmates.com provided INSIDER with many high school yearbook photos and some of their superlatives.

Some of what we learned was unexpected: "The Martian" star Jessica Chastain dropped out of high school and Melissa McCarthy went through a goth phase in her final two years of school. And did you know that Bill Murray paid his way through Catholic school?

Keep reading to see what your favorite celebrities were like and what they were doing in high school.

That may have been because Willis was voted president of Student Council. The actor also played baseball and was part of the drama club, acting in some of the school plays. Willis found it to be therapeutic.

"I had a horrible stutter when I was a kid, from the time I was 9 until the time I was about 17. And a miraculous thing happened when I was in high school," told Reader's Digest. "I was doing this goofy play. It wasn't a goofy play, we just did it in a goofy way. Connecticut Yankee in King Arthur's Court. When I got onstage, I stopped stuttering. When I stepped off the stage, I started stuttering again. And I went, 'This is a miracle. I got to investigate this more.'"

She told The Hollywood Reporter her real passion was dance and she pursued that after high school instead of furthering her education before she began acting.

"I didn't go to the university because there weren't options in my family. And I stopped the athletic options. I was supposed to stick with track because I was really quick and I could run fast, but I told them, 'I want to dance.'" said Adams in 2008. "I taught kids when I was in high school. That's how I paid for my dance classes. I worked in a dancewear store. I just waited to get out of school. I wasn't one of those people who enjoyed being in school."

Clooney told Larry King he had bell's palsy, where half of his face was paralyzed, when he first started high school at age 13.

"It takes about nine months to go away," said Clooney who came down with symptoms after watching the film "The Pride of the Yankees." "It was the first year of high school, which was a bad time for having half your face paralyzed."

The actor told Esquire he was a good student, receiving A's and B's, at least in elementary. "I was a much better student than I thought I was. I had all A's and a B. So that's not so bad," said Clooney in 2008.

Clooney was also part of drama club and was prince of his senior prom.

His buddy Brad Pitt was one of the popular kids and was voted best dressed.

According to "Brad Pitt, Biography of a Superstar," Pitt received good grades while playing tennis, golf, and being a part of the debate team. Pitt also acted in school plays and musicals. Despite being in the movie "Moneyball," Pitt wasn't a baseball player, but he did play a few other sports.

"Baseball and I didn't get along that well," he told Sports Illustrated. "I wrestled one year. I dove one year. Everything but baseball."

Oprah Winfrey was voted most popular.

Winfrey attended several different high schools growing up. She graduated from East High School in Nashville, Tennessee where she was in the Honor Society, National Forensic League, and was in the student government.

Meryl Streep was the homecoming queen when she was 17.

Streep went to Bernards High School in Somerset County, New Jersey, where she was a cheerleader, and participated in plays like "Oklahoma!" and "The Music Man." She also did gymnastics among a long list of extracurriculars, but in no way would she have considered herself the popular girl.

According to Michael Schulman's "Her Again: Becoming Meryl Streep," Streep said while young, kids would "chase me up into a tree and hit my legs with sticks until they bled" and thought she was "ugly."

Streep turned to magazines like "Seventeen" and "Vogue" to transform herself in high school and opened up about her evolution during a 2010 commencement speech at Barnard College.

"Empathy is at the heart of the actor's art," said Streep. "And in high school, another form of acting took hold of me. I wanted to learn how to be appealing. So I studied the character I imagined I wanted to be, that of the generically pretty high school girl."

Snoop Dogg and Cameron Diaz actually attended the same school, though he was a grade above her. On an episode of George Lopez's old late show, she claimed that he once sold her some weed. Snoop said it probably happened.

Nicolas Cage said he was a straight-A student until he lived with his famous uncle.

Cage told the New York Times in the early '90s he was a straight-A student until he moved in with his uncle Francis Coppola for a year after his parents divorced and he went to a small country school.

"I went suddenly from being the cool guy to the geek. My grades went from straight A's to straight F's," he said. "I was in this wonderful house with wonderfully generous people, but it wasn't my stuff, it wasn't my house. I didn't know why I was there. I was frustrated beyond belief."

Ellen DeGeneres wasn't fond of school.

"I hated school," she told New Orleans magazine in July 1994. "I started college because everyone else was going. I majored in communications, I think. Or communications and drama. And I just remember sitting in there, and they were talking about the history of the Greek theater or something, and thinking, 'This is not what I want to know.'"

"I was pretty lame, though, and much more of a goody-two-shoes than I looked," she told Rolling Stone. "Maybe occasionally I'd make out with some guy, but never anything further. I was usually the dork surrounded by a bunch of my gay friends."

"I acted like a maniac and looked like a really angry, violent punk," she added. "But I was always too chatty to be really angry."

Spacey moved around a lot as a kid with his family growing up, but took an interest in drama and music. He went to several high schools, including Canoga Park High School, where, when he was in 11th grade, he had an epiphany during a performance of Arthur Miller's "All My Sons."

"Something happened as I walked off the stage that had never happened to me before. The audience applauded me in the middle of the play. It was the first time I realized I had an effect on people," Spacey told Parade. "It was puzzling, confusing, slightly frightening, and it was liberating. Finally acting gave me something to focus on, something I enjoyed that offered me a chance to go into different worlds. All these imaginary games that you played with your friends in the neighborhood — I didn't have to put those games away. I just kept playing them onstage."

He then transferred to Chatsworth High School in California his senior year where he became co-valedictorian.

Her high school boyfriend, Rhett Baker, told the DailyMail in 2014 Zellweger was a well-rounded, popular varsity cheerleader and track runner.

"She was in multiple crowds because she was very good at multiple things," said Baker. "People respected that. She didn't flaunt that."

"When you put her on stage she had the biggest personality in the room," he added. "Beyond that she was much more reserved than a lot of people and that was one of the things even back then a lot of people would talk about."

Foxx, whose real name is Eric Marlon Bishop, had aspirations to play for the Dallas Cowboys. In high school, he played basketball and was a quarterback on the football team. He was the first player in his school to make a pass for over 1,000 yards.

However, music was also a big part of his life. Foxx was also a part-time pianist and choir leader at his baptist church. In addition, he was in a short-lived band called Leather and Lace. Foxx ended up receiving a music scholarship from the United States International University.

Jessica Chastain dropped out of high school.

"I was not a hard worker. I was a terrible student. Eventually I got my adult diploma, but I did not graduate. And it wasn't that I just dropped out and never went back—at the end of the year I had too many absences to graduate," Chastain told Entertainment Weekly.

Chastain said she often skipped school and sat in her car reading Shakespeare.

Robert Downey Jr. also dropped out of high school.

According to "Born to Be an Actor," Robert Downey Jr. had poor grades and school attendance coupled with drug and alcohol use. When he was told at the end of 11th grade he'd have to attend summer school to graduate, Downey Jr. decided to drop out to pursue an acting career in New York.

"For me, you know, growing up in school was just, you know, smoking pot all the time," said Downey Jr. in a CNN profile. "I consider myself someone who needs to express himself creatively, and acting seems to be the most lucrative and attention- getting way of working it out right now."

"I would take knitting classes and crocheting classes at the local community center, because it was something to do," she added. "But also, you need a kind of positive conduit to just release all that pent-up energy and frustration, because it's frustrating being poor. You don't have access to things, and you're not seen in a great light ... It really helped me to be able to express myself, and to be kind of rewarded for expressing myself well. It kind of built my self-image. I was so painfully shy."

After his parents divorced, Washington's mother sent him to a private boy's high school and he said it was one of the best things that could have happened to him.

"I wouldn't have survived in the direction I was going," Denzel told Parade magazine in 1999. "The guys I was hanging out with at the time, my running buddies, have now done maybe 40 years combined in the penitentiary. They were nice guys, but the streets got them."

"I loved school, maybe too much really. I was summa cum laude in high school," Williams told the Detroit Free Press in 1996. "I was driven that way. I can't say it was easy to fit in. I just went out of my way to fit in. It was a private boys school, Detroit Country Day, and I played soccer. I was on the wrestling team. Mr. All-Around, you know?"

The singer started writing lyrics in high school and went by the name Professor Macklemore, a name he came up with for a project.

"Garfield was just a wild school. The teachers had given up before they had even started," Macklemore told Complex in 2012. "Classes were hella disruptive. Nathan Hale was more tamed. I needed a school like Nathan Hale. Because being kind of the kid [who] was getting into drugs and was rebelling against whatever my teachers said or whatever my parents said, getting into fights."

"Hale took me out of my environment. I didn't really have friends there. I never really liked it," he continued. "It made me focus on music. That's when I really didn't have else to do. I kind of stopped smoking weed at school. It just became more about writing raps and focusing on music."
